The series 221X, 222X, 223X of thermostatic expansion valves have been designed to work with interchangeable nozzle units to ensure their flexibility in terms of output selection. They are available with liquid loads and with MOP load, with two different evaporation temperature intervals: -40 to +10 °C and -60 to -25 °C. They can be used for a wide range of applications that use the following ASHRAE 34:2019 Class A1 refrigerants:
Maximum allowable pressure PS = 34 bar.
Allowable temperatures TS = -60 to +120 °C
